Planning the reconfiguration of grounded truss structures with truss climbing robots that carry truss elements Citation

In this paper we describe an optimal reconfiguration planning algorithm that morphs a grounded truss structure of known geometry into a new geometry. The plan consists of a sequence of paths to move truss elements to their new locations that generate the new truss geometry. The trusses are grounded and remain connected at all time. Intuitively, the algorithm grows gradually the new truss struct...

Vertical load capacities of roof truss cross members.

Trusses used for roof support in coal mines are constructed of two grouted bolts installed at opposing forty-five degree angles into the roof and a cross member that ties the angled bolts together. The load on the cross member is vertical, which is transverse to the longitudinal axis, and therefore the cross member is loaded in the weakest direction. Laboratory tests were conducted to determine...

Truss-based Community Search: a Truss-equivalence Based Indexing Approach

We consider the community search problem defined upon a large graph G: given a query vertex q in G, to find as output all the densely connected subgraphs of G, each of which contains the query v. As an online, query-dependent variant of the well-known community detection problem, community search enables personalized community discovery that has found widely varying applications in real-world, ...

Decision Support System for single truss tomato

Engineering and horticultural research efforts aimed at developing an innovative, controlled environment, plant production system have been completed. In this production system, tomato plants are made transportable and each plant is allowed to produce only one truss of fruit. The main objective of this production system is to secure uninterrupted and predictable quantities of uniform quality to...

Truss Assembly : Motion Control

The nonholonomic motion planning problem is considered for a novel class of modular mobile manipulators, where each module is implemented as a planar parallel manipulator with idler wheels. This assembly is actuated by shape changes of its modules, which, under the in uence of the nonholonomic constraints on the wheels, induce a global snake{like motion of the assembly. The kinematics for a 2{ ...
